How often do you apply lip chap to your lips?

Some people always seem to have chapped lips. I don’t think anyone actually takes notice of the amount of times they apply lip chap, or lip gloss… but I was just curious to see if I apply lip chap too often.

I think I apply and re-apply quite often throughout the day. After meals, or whenever I think it has gotten rubbed off somehow, or when it’s just dry. I don’t actually count though. When do you? I carry some sort of lip chap/gloss around with me in my bag, or backpack.
